David, I’m sorry I sounded rather negative with my comment. It really is a very good website but I was frustrated as I had spent a long time searching for information on the colour coding of the routes shown. I eventually found this forum entry where you note the three colours, red, blue and purple, as excellent, good and other. However, your map of Northern Spain which I was looking at has other route colours too ...brown and orange. What are these?

It would be helpful to have the colour-key somewhere where it can be easily seen, the site would then be brilliantly useful.
